Full Answer

Elements are arranged in the periodic table into 18 groups or families (vertical), and seven periods (horizontal). Elements are listed in the periodic table depending on their atomic structure. Elements in the same group or family have the same number of outermost electrons which gives them similar physical and chemical properties, while elements in each period have gradually changing chemical properties owing to the progressive rise in atomic mass from left to right.

  • Q:

    Why was the periodic table invented?

    A:

    The periodic table was invented by chemist Dmitri Mendeleev to organize and compare elements and understand their relations with each other. Mendeleev created the periodic table between 1868 and 1870 while writing his book titled "The Principles of Chemistry." Initially, Mendeleev created the chart for his personal benefit, but others quickly discovered its value, leading to its immediate acceptance and use by fellow chemists upon publication.
